DANIEL POMEROY, OF BROOKLYN, NEW YORK.

TRUSS.

To aZZ whom it may concern:

Be it known that I, DANIEL POMEROY, a citizen of the United States, anda resident of the cityof Brooklyn, in the county of Kings and State ofNew York,have invented a new and useful Improvement in Hernia-Trusses,of which the following is a specification.

My invention relates to the connection of the pad which .bears on theorifice of protrus1o n with the spring or bandage which keeps it 1nplace and it consists in the improved construction and arrangements ofthe devices of said connection hereinafter described and claimedreference being made to the accompanying drawings, in which Figure l isa front elevation of a pad and part of the spring-bar or metallictruss-band to which it is connected. Fig. 2 isa sectional elevation ofthe pad on line 00 x, of Fig. 1, and side elevation of a standard whichis one of sald connecting devices. Fig. 3 is a transverse section of thepad, truss-band, and a clamp also forming one of said connecting deviceson line y y, Fig. 1, and a side elevation of the aforesaid standard, andFig. 4 is a horizontal section of the clamp on line 2 2, Fig. 3.

It is my purpose to provide a simple, reliable and easily adjustableconnection of the pad 60, with the truss-band b, that may be readilyconnected and disconnected and in which the pad will oscillate freely inthe plane of its largest diameter, but will not oscillate in theshortest or transverse diameter, as it would if the standard 0 wereconnected to the pad by a universal joint, and may be readily turned onthe axis of the standard and slid upon the truss-band for adjustment,temporarily retaining any desired position while being adjusted, andthen be effectually clamped and secured in the position in which it isset. To these ends the standard 0 is bored through transversely at n,Figs. 2 and 3, suitably to fit and turn snugly on a rod cl which issecured by rivets g, or otherwise, to the inside of the pad plate ftransversely of the latter, a recess 6 being made in the pad 0. toreceive the rod d. In connecting together the standard and pad theformer is inserted through a hole 0 in the pad-plate f; the rod d isthen put through the hole n in the standard and secured to the plate fas at g. The

SPECIFICATION forming part of Letters Patent No. 505,228, datedSeptember 19, 1893.

plate f is then secured to the pad a by screws 8, Figs. 1 and 2. Thehole 0 in the platefis sufficiently enlarged in the longitudinaldirection of the pad, as seen in Fig. 2, to allow the desired freedom ofoscillation. By this construction it is evident that oscillation of thepad can take place in the lengthwise direction only.

a On the other end of the standard I provide the flat circular ordisk-shaped head It having an annular rabbet or recess in the lowerportion of its perimeter forming the shoulder 11 and with thestandardthus constructed and the metallic truss-band b, the form of which isflat in the portion to which the pad is to be connected, I provide theclamp consisting of theyoke j, and clamp screws to clamp and secure thestandard and truss band together,

said yoke being a fiat bar having the end portions Zdoubled backparallel with the middle portion, but not quite meeting together, so asto admit standard 0 between them, and being recessed on the inside, asindicated at m, about the depth of the height of shoulder '5, so thatthe larger part of the head above shoul' dert, overlaps and bears on thesurfaces of the parts Z surrounding the recess while the shoulder reststherein.

It will be seen that the space between the ends Z of the clamp allowsthe standard to be entered freely between them and the recess mconstitutes a bearing in which the standard is confined by the shoulder'6 under the head when placed therein, and the truss-band h is insertedin the clamp over the head It and pressed down upon the latter by theadj usting screws is screwed in against it, and thus also at the sametime pressing down the upper larger portion of the head upon the surfacesurrounding the recess to secure the pad very efficiently againstturning when the screws are tightened,-and the recess m constitutes apivot-bearing in which the standard may be turned freely to adjust it tothe re quired position before setting the screws in tightly. The pad isalso adjustable lengthwise along the truss-band while the screws areslack.

I claim The combination with the pad and the truss band, of thestandardfor connecting the pad to the said band, said standard beingpivoted upon a bar arranged in a recess in the said pad transverselythereof, and secured to the inside of the pad-plate, and said platehaving ahole to receive the standard and allowlength- 5 wise'oscillationof the pad, substantially as described.

In testimony that I claim the foregoing as my invention I have sign edmy name, in presence of two witnesses, this 20th day of April, 1891.
